Uart Problem about DTM Project for NRF5340

[yfyh0727]

Hi,

I want to use dtm project to test RF PHY performance about NRF5340. But after downloading dtm project and empty app project, NRF5340 can work normally from output RTT log. But when I sent command to BLE board by uart, there is no response. I can confirm there is no data in rx_byte buffer from RTT log. The uart configuration is following:

&uart0{

            status = "okay";

            current - speed = <19200>;

            tx-pin = <25>;

            rx-pin= <26>;

            rts-pin = <10>;

            cts-pin = <12>;

};

Please help me to check the uart configuration. And if there is other configurations about SW&HW, please tell me.

Thank you!

What tag/commit are you on? I'm struggling to get the RTT logging to work on NCS  v1.4.0. Could you tell me how you achieved this?

Best regards,

Simon

Hi,

I used tag v1.4.0. The DTM project have defult configuration about RTT logging. So If the dtm project can run normally, you can get RTT logging. The detail information about how to get RTT logging is in Nordic website and you can refer to it.

I'm sorry for the long delay on this, I've been quite busy lately. Have you made any progress or do you want me to look into this?

Best regards,

Simon
